- rnocms AND ArrARArUs FOR CASTING HOT LIQUID Mum.

To all whom it may concern; I Be it. known that I, JOHN L. MAUC-H, a citizen of the United States, residin at Brooklyn, in the county of Cook and tate of New York, have invented or'discovered certain new and useful Improvements in iquidMaterial, of which the following is to the accompanying drawings. This invention relates to the handling ofhot liquid materials and especially, ,al-

. provide a method and means whereby molten sulphur and other materials having similar prolperties may be quickly and inexpensively coo edand solidified and delivered in a convenient form for storage or further handling.

The'foregoingand other-,objects of the invention, together with one mode of carrying the same into effect, will best be understood the arapp-aratus illustrated in the accompanying drawings. It'will be understood, however, that the particular constructions and operabeen chosen for illustrative purposes merely, andthat the invention, as defined by the claims hereunto appended, maybe otherwise practiced without departing from the spirit and scope thereof; In said drawings: 1

v Fig. 4 is a plan view of the container shown in Fig. 3 with'the coverremoved. w

Referring to, Fig. 1, the hot liquid sulphur or other material from any suitable source is delivered through an inlet conduit 10 to' a receptacle or container 11 having an overflow 12, whereby the liquid level, in said 60 be mainta ned substantially container may constant. The container :1 double wall providing. a heatpreferably ing jacket 13 which may be supplied, asat 14,'with-stea1n.o r other healing-fluid, said container having I a heat-insulating jacket jacket 13 1s retained. provided with one or more, but preferably a plurality of discharge, outlets or nozzles, 17 i which preferably communicate withthe in tenor of said container at different levels heat supiplied thereto by the f he containerll is and extend through the heating jacket 13,

a position to receive 23, one of which may be positively driven by any suitable means (not shown) to cause direction indicated by the arrows, and'one of which, preferably the pulley 23, may be a take-up pulley to keep slack out of the'belt.

In accordance with the invention, the belt 19, or the. material receiving surface thereof,

is preferably composed of rubber or its equivalent, or of a suitable fabric 1mpregnated-with rubber or the like,

so as to present-"a compact, non-fibrous, and preferably elastic surface towhich, it is sulphur will not adhere to an objectionableextent, ifsaid surface be cooled and wetted prior to the deposit of .the sulphur thereon. To this end the lower reach ofsald belt is preferably arranged to pass through a water Said belt 19 passes about p'ulserves to supplyheat to-said I said belt to travel in the found, the hot tank 24, or there maybe provided a pipe 25 adapted to deliver water to the sulphur re- Y it is struck by for breaking the leaving the belt or carrier 19. there may, i

ceiving surface of said belt preferably in the form of a spray, or, if desired, both the tank 24 and pipe 25 may be employed.

The nozzles 17 for depositing the liquid material upon the upper reach of the belt 19, when more than one of said nozzles are employed, are arranged in a series disposed parallel to the direction of travel of said belt or carrier in such a manner as to deposit the material from the container 11 upon said belt or carrier in successive layers. Eaci layer so deposited is cooled prior to the deposit of a succeeding layer by jets or blasts of a suitable cooling fluid, preferably air, delivered by pipes 27 located between the said nozzles and beyond the last'nozzlein the series. Said nozzles 17 are formed with narrow discharge slots 52 disposed transverse to the belt 19 (see Fig. 2) so that the material is deposited on said belt in thin layers, which, together with the cooling effectof the air blasts from the pipes 27. and the precooling of that surface of the belt upon which the material is deposited by the water in the tank 24 and that supplied by the pipe 25, causes the sheet of material on said belt to cool throughout very quickly, so that, when'said material is brought to the discharge end of the upper reach of the belt adjacent the alley 21, it willhave become fully solidified As the belt passes about 'the pulley 21 it is drawn away from the sheet ofsoliditied material, which it leaves readily by reason of its initially wetted rubber surface. said sheet projecting beyond said pulley where a series of centrifugal ha'mcarried by a rotating shaft 29 disposed adjacent the pulley 21, said sheet being broken by said hammers into pieces of convenient size which are permitted todrop into a suitably disposed hopper 30 or other receptacle.

In order to furnish a point of reaction sheet of solidified material mers 28 pivotally desired. be employed a. weighted roller 2-31 carried by suitably pivoted links 32 and resting upon the material on the belt adjacent the pulley 21.

Any liquid material which may spill from the edges of the belt 19 may be caught by a suitably arranged trough 3?) and delivered thereby to the tank 24. which constitutes a sump for collecting such material. As herein shown the upper end of said trough is supplied with waterthrough a pipe 26 which water serves to wash the material into said sump as well as to supply the tank 24.

ln order to remove from the surface of the belt 19 any particles of material still adherii-ig thereto after leaving the pulley 21. there is provided in the tank 24 a rotary brush Ill engaging the material receiving surface of said belt, said brush also engaging a stationary cleaning bar 35, whereby the particles of belt by said material removed from said brush are disengaged from the latter.

In the arrangem 4, the contalner 4.0 f

is supplied by preferably an inlet 41 u of a float valve 42, and sa provided with a jacket 43 and cover able steam coils 15.- ings of said container, which correspond in ent shown in The discharge openarrangement to the nozzle 17 shown in Fig.

1, comprise wells having dams 46, preferably formed with corrugated surfaces, and arranged with straight upper edges, which determine the effective position 0 at substantially the liquid by the float valve ing cylinder 47 42. Within 40 adjacent each of said dams Figs. 3 and or the molten material nder the control id. container is heat insulating and is heated by suitf the outlets, level controlled the container 46 is a rotat- 7 mounted on a shaft 48 con- ,nected by suitable bevel gearing 49 with an from any suitable source to rotate the cylinders 47.
